Crowd outside L'Enfant Plaza Metro station on the way to the National Mall

WASHINGTON (WUSA) -- Fewer riders expected this year than for the 2009 presidential inauguration of Barack Obama, but there will be station closures and other transportation adjustments. Three Metro stations will be closed: Smithsonian, Archives and Mount Vernon Square. Rush hour and the coinciding fares will be in effect from 4 a.m. through 9 p.m. Service runs until 2 a.m. Tuesday.

Metro tweeted from @MetroInaug that as of 7 a.m., 89,000 people had entered the system. It also reported that heavy crowds were reported at Federal Center SW, tweeting: "Please use Federal Center SW only if you hold an Inauguration Day ticket. L'Enfant Plaza is your best alternate if you are not ticketed."

WUSA 9's Delia Goncalves gave an update on the number around 9:45 a.m., saying there were more than 113,000 people were counted on Metro's system so far.

The Metro ridership rate surpassed the halfway mark of 2009 levels at 10 a.m. with more than 266,000 people, according to @MetroInaug.

At approximately 11 a.m., Metro reported the 7th and D entrance at L'Enfant Plaza was temporarily closed due to crowds at the U.S. Secret Service's request. It later reopened.

Delia Goncalves reported from the New Carrollton Metro stop early Monday morning. She caught up with one family who was bundled up and ready to go. Delia also says she spotted plenty of people who were carrying items that may be prohibited in some areas in D.C. today. Check the list of prohibited items here: http://on.wusa9.com/WyZcyA
